As a Mac user, I find this arguable. Many of the color correction comes from the fact that Macs contain ICC profiles for tons of monitors. OTOH, if the monitor is already has accurate color rendering out of the box (e.g.: Dell UltraSharp, HP EliteDisplay), Linux (esp. KDE) has very high display quality on HiDPI monitors, too.
